TECHNICAL FIELD

The present invention relates to natural invigorating, tea products anda method for preparing the same. More particularly, the presentinvention relates to invigorative teas made of certain parasitic plants,alder and/or schizandra and a method for preparing the same.

PRIOR ART

Human beings are mentally and physically affected by various externaland internal factors. Those factors are, weather, biosocial environmentsand nutritional conditions. Occasionally, the effect is exerted as astress on the human body. Stress is said to be a stimulus or successionof stimuli of such magnitude as to tend to disrupt the homeostasis ofthe organism. In these days of multifunctional information-orientedsociety, human beings undergo various stresses, caused by physical,chemical and biological or emotional stimuli. Recent reports haverevealed that men who are under severe or extensive stress become poorin virility due to reduction in their sperm concentration and spermmotility.

Generally, sperm motility is taken as an indicator for sperm viability(Noran et al., 1998), while semen motility is evaluated in terms ofsperm concentration, percentage of morphologically abnormal sperms,ratio of living to dead sperm, semen volume, pH, initial vitality ofsperms, and mass movement of sperms (Berndtson and Pickett, 1980).

After making an examination of sperm conditions of 50 persons in theirtwenties (24 years old on the average) and 44 persons aged 37-53 (42years old on the average), who lived near Tokyo, Japan, the MedicalCollege of Teikyo University, Japan, made a research report whichcontained a surprising result that the men in their forties had about 84million sperm cells per ml on the average while the men in theirtwenties had a sperm count of as low as 46 millions, which is only 55%of the 40-49 age group's average. Also, it is found in the researchreport that all of the men aged around forty were capable of procreationby the criteria reported by WHO in 1992 that the minimum sperm count forconception through ordinary sexual intercourse must amount to 20 millionper ml, whereas only 86% of the men in their twenties satisfied thiscriteria. Similar sperm motilities were detected in the men in theirtwenties and forties: 27% and 28%, respectively.

However, sperms produced by the men in their twenties were measured tohave a normal morphological ratio of 52%, which was lower than that ofthe men in their forties, measured to be 64%.

Also, the research report disclosed that the average sperm count of themen in their twenties and thirties had sharply reduced in comparison tothat of men of the same ages 20 years ago, which were reported to havean average sperm count of 75 to 100 million in a similar research,adding that Japanese men had also suffered from the worldwide spermcount reduction phenomenon and that endocrine disruptors, calledenvironmental hormones had been deduced to play an important role in thesperm count reduction.

Indeed, it has been known that the average sperm count from human malesis 60% lower compared with 50 years ago. According to the report made byDr Scott at the Copenhagen University Hospital in 1990, in a study for14,000 men, it was found that the average sperm count was reduced to 66million/ml with an average semen volume of 2.7 ml, representing a sharpreduction from the values of 110 million/ml and 3.9 ml respectively in1940.

This sperm count reduction phenomenon was also confirmed by Dr. Auger,in France. He said that average sperm counts had dropped to sixtymillion in 1992 from eighty nine millions in 1973 with a reduction rateof 2.1% per year.

If the sperm counts of men continue to drop at this rate, mankind willface a sterility crisis, threatening its continued existence, within 60years.

Having been regarded as a symbol of masculinity, being vigorous orhaving stamina is helpful in maintaining men's health, as well as intheir having sexual intercourse for preservation of the species or forpleasure.

Amid the current deluge of processed foods seasoned with chemicals,especially precooked foods, people tend to avoid natural foods. However,it is well known that one of the methods to retain the spirit and energyreceived from the natural system is to maintain a regimen of eatingnatural foods.

Artificially synthesized chemicals for use in industry and agriculturehave long been known to have an abnormal influence on the workings ofthe endocrine systems of human beings and animals. Indeed, animals whichare problematic in development, behavior or genital morphology owing toendocrine disruption, are now frequently found. This matter of graveconcern is highly apt to happen to human beings. The chemicals aregenerically called endocrine disruptors, more well known asenvironmental hormones.

On the other hand, with an increase in interest about sex, some peopleseek to enhance their sexual potency by means of drugs or the like. Inresponse to this tendency, a number of drugs are now commerciallyavailable. For example, medications have been developed to treaterectile dysfunction (impotence) in men. Also, people can obtain creamformulations to enhance sensual pleasure. In addition, it is suggestedthat alcohol improves human sex life because of its ability to relievethe tension of the nervous system. However, such drugs have manyproblems. The medication for treating impotence may be fatal to thosewho suffer from hypertension. Cream formulations are inconvenient foruse in addition to being expensive. Alcohol users may be in danger offalling into alcoholism.

In the above tea examples of preparing the natural tea productsaccording to the present invention, it is noted that the sameextractant, water or ethanol, was used for the different materials ineach example as in the example 1 through 48. However, it is of coursepossible to use different extractants for the different materials orherbs adopted in the same example.

After hosts of experiments with various compositions of the parasiticplants and alder and/or schizandrae fructus, extracts comprising 20-80%by weight of the parasitic plants and correspondingly 80-20% by weightof alder and/or schizandrae fructus were found to be preferablyeffective in invigorating the body.

Also, a preferred invigorating effect could be obtained when polygalaejaponica herba roots and/or torilis fructus was present at an amount of10-70% by weight based on the total weight of the materials used.

As described above, the herbal materials can be steeped or extractedseparately or in a mixture of them with a preference to an extractionratio of 40-120 cc/g. As for the extractants, they must be aqueous andedible like water and ethanol. The extraction period of time depends onthe concentration of ethanol in the extractant. It should be understoodthat the extraction period of time can not be a reason for limiting thescope of the present invention.

Of the parasitic herbs, the herbal material indispensable for thepresent invention, Lathraea japonica Miq. was found to be more effectivein invigorating the body than the other two species, Orobanchecoerulescens Steph. and Boschniakia rossica Fedtsch., the former beingmore effective than the latter.

Compared with a natural tea comprising an extract from either polygalaejaponica herba roots or torilis fructus, a natural tea comprisingextracts from both polygalae japonica herba roots and torilis fructusshowed a further improved invigorating effect.

Differently from the above examples, the same materials as used in theabove-described examples may be steamed and dried so as for theresulting mixture to be soaked in boiling water to give a natural teaaccording the present invention. Preferably, the mixture isfreeze-dried. Alternatively, the mixture of the tea materials either inthe natural state or in the steamed state may be powdered to give anatural tea according to the present invention, as claimed in theaccompanying claims.

As for the alder, all its parts, including fruits, sprigs, leaves androots, were found to be effective although the fruit was not included inthe above description and the alder extracts as described in the claimsmean all parts of alder as above.

In addition to roots of polygalae japonica herba, its leaves and stemsare useful in the present invention. Even in the case of torilisfructus, its roots as well as fruits were found to be effective ininvigorating the body.

In order to improve the taste or flavor of the natural tea according tothe present invention, additives such as sweeteners and flavorings maybe added to it.

CONTROL EXAMPLE

Boschniakia rossica Fedtsch. was cleaned and chopped to pieces, afterwhich 4 g of the chopped Boschniakia rossica Fedtsch. was steeped in amixture of 250 ml of 95% ethanol and 160 ml of water at 60° C. for 6hours to give 150 g of an extract.

EXPERIMENTAL TEST

An experimental test was carried out to confirm the invigorating effectof the natural tea products of the present invention. Each of 87 men intheir forties to seventies was allowed to drink 140 ml of a natural teaof this invention twice a day, after breakfast and just before sleepingfor 30 days and then effects of the teas on the sex life the subjectswere measured. For comparison, the tea prepared in Control Example wasused as a control. The results are given in Table 1, below.
